hi @TurboC welcome to the community 🤝

and like always - [search](https://help.nextcloud.com/search) helps - lot of issues have been discussed already!

this is not the right mount destination. From the [docs](https://github.com/nextcloud/docker#persistent-data) you see

> `/var/www/html/` folder where all Nextcloud data lives

you want to persist more than files only e.g. config is essential 😉

Nextcloud runs by default with user 33:33 I would recommend to assign this user and correct permissions (folders:750, files: 640) to all data mounted into NC container. Newer versions can run with a different UID but this requires more tweaking.
